The impact of carbon capture and storage on a decarbonized German power market

Spiecker, S.; Eickholt, V.; Weber, C. - In: Energy Economics 43 (2014) C, pp. 166-177

The European energy policy is substantially driven by the target to reduce the CO2-emissions significantly and to mitigate climate change. Nevertheless European power generation is still widely based on fossil fuels. The carbon capture and storage technology (CCS) could be part of an approach to...

Energy-constrained Mean Field Games in Wireless Networks

Tembine, Hamidou - In: Strategic Behavior and the Environment 4 (2014) 2, pp. 187-211

This article is part of a Special Issue on ICT-based Strategies for Environmental Conflicts. In this paper, we study anti-jamming problems in energy-aware wireless networks using mean field stochastic games. We consider three types of users: jammers, primary users and secondary users. When...

Cut-off grade: A real options analysis

Thompson, Matt; Barr, Drew - In: Resources Policy 42 (2014) C, pp. 83-92

In this paper we examine the impact of forward price uncertainty on the optimal cut-off policy of mines. We employ a new real options model for determining the optimal cut-off grade of ore under stochastic prices. The economic insights and consequences of incorporating uncertainty into the...

The future of the European electricity system and the impact of fluctuating renewable energy – A scenario analysis

Spiecker, Stephan; Weber, Christoph - In: Energy Policy 65 (2014) C, pp. 185-197

The ongoing transformation of the European energy system comes along with new challenges, notably increasing amounts of power generation from intermittent sources like wind and solar. How current objectives for emission reduction can be reached in the future and what the future power system will...

A probability constrained multi-objective optimization model for CCHP system operation decision support

Hu, Mengqi; Cho, Heejin - In: Applied Energy 116 (2014) C, pp. 230-242

stochastic optimization models have been proposed to study the CCHP operation strategy. However, fewer studies have been …

Optimal grid design and logistic planning for wind and biomass based renewable electricity supply chains under uncertainties

Osmani, Atif; Zhang, Jun - In: Energy 70 (2014) C, pp. 514-528

In this work, the grid design and optimal allocation of wind and biomass resources for renewable electricity supply chains under uncertainties is studied. Due to wind intermittency, generation of wind electricity is not uniform and cannot be counted on to be readily available to meet the demand....

Macroeconomies as Constructively Rational Games

Sinitskaya, Ekaterina; Tesfatsion, Leigh - Department of Economics, Iowa State University - 2014

Real-world decision-makers are forced to be locally constructive, in the sense that their actions are constrained by the interaction networks, limited information, and computational capabilities at their disposal. This study poses the following question: Suppose utility-seeking consumers and...
